13 This manpage documents briefly the fityk and cfityk programs for non‐
14 linear fitting of analytical functions (especially peak-shaped) to data
15 (usually experimental data). In other words, for nonlinear peak separa‐
16 tion and analysis.
17 It was developed for analyzing diffraction patterns, but can be also
18 used in other fields, since concepts and operations specific for crys‐
19 tallography are separated from the rest of the program.
20 Fityk offers various nonlinear fitting methods, subtracting background,
21 calibrating data, easy placement of peaks and changing peak parameters,
22 automation of common tasks with scripts, and much more. The main advan‐
23 tage of the program is a flexibility - parameters of peaks can be arbi‐
24 trarily binded with each other, eg. width of peak can be an independent
25 variable, can be the same as width of other peak or can be given by
26 complicated - common for all peaks - formula.
27 The program comes in two versions: fityk , the GUI version and cfityk ,
28 the command line version.
29 A user manual for fityk and cfityk can be found in
30 /usr/share/doc/fityk/html/fityk-manual.html.
